Working Principle Safety CPU sends safety commands to F3430 module via safety backplane bus. The module energizes or de-energizes relay coil according to safety command, so relay contact closes or opens to control field safety load. The diagnostic circuit monitors coil current and contact feedback continuously to detect wire break, short circuit and relay contact failure. When fault is detected, module sends fault report to safety controller and triggers LED fault indicator.
Installation Requirements
- Install module into HIMatrix F35 DIN rail rack.
- Use shielded twisted pair cable for field safety load wiring.
- Separate safety relay wiring from high power motor cables.
- Complete protective earth connection for rack and cabinet.
- Verify wiring polarity and load specification for field equipment.
- Perform channel fault simulation test after installation.
- Check backplane bus connection before power energization.
Usage Notes
- Do not hot plug module outside approved hot-swap configuration.
- Do not exceed rated voltage and current specification of relay contacts.
- Add surge suppression components for inductive loads connected to relay contacts.
- Keep cabinet dry and free of corrosive gas and conductive dust.
- Execute periodic SIL proof test according to safety procedure.
- Disconnect field wiring before high voltage insulation test.
- Replace module immediately when relay contact sticking or burning occurs.
